油气储层识别软件的研制

基于软件工程理论,结合计算机软件技术和油气储层识别技术,选用Motif作为开发平台,研制了Unix操作系统下的油气储层识别软件。针对大型物探软件的特点,采用结构化的文件系统进行数据管理,引入全PlugIns概念合理设计系统架构,确保了软件质量,有效地延长了软件的生命周期。在软件的编制过程中,整合了地震属性提取及优化、BP神经网络、SOM聚类分析、叠后波阻抗和叠前弹性反演等油气储层识别的先进技术,建立了油气储层判别工作流程。此软件已应用于实际地区,并取得了良好的应用效果。同时该软件也为其他技术的集成提供了一个基础平台。

Development of oil and gas reservoir identification system

Combined reservoir identification technology with computer science technology, the software named oil and gas reservoir identification system was developed on the basis of the thinking of software engineering by using Motif as the platform under Unix system. Considering the characteristics of large-scale geophysical prospecting software, the filing system was adopted to manage the data, the concept of entire PlugIns was introduced for designing the reasonable construction of the software, through which the quality of the system can be guaranteed and its lifecycle can be extended. This system establishes the work. flow of discriminating the oil and gas reservoir tentatively. This system consists of some advanced technologies of reservoir identification, such as seismic attribute extraction and optimization, BP network, SOM clustering analysis, poststack and pre-stack inversion, and offers a foundation platform for integrating other geophysical technologies. Good effect was obtained in practical application.
